Microsoft 365, formerly known as Office 365, is a powerful suite of cloud-based productivity tools, that has revolutionized the way we work and collaborate. From email and document creation to video conferencing and project management, Microsoft 365 offers a comprehensive set of tools that can help individuals and organizations of all sizes be more productive, efficient, and collaborative.

If you’ve read our previous blog on How to Buy Microsoft 365 from ZNetLive, your next question would be how to add a domain in your Microsoft 365 Admin center?

Why a custom domain? Adding a custom domain can help to give your email and website a more professional look. However, adding a domain can seem like a daunting task, especially if you’re not familiar with the Microsoft 365 Admin Center. Fortunately, the process is relatively straightforward once you know what to do.

In this step-by-step guide, we’ll walk you through the process of adding a domain to your Microsoft 365 Admin Center, so you can get started with customizing your email and website.

How to Add Domain in Your Microsoft 365 Admin Center?

Configuring the DNS records and assigning users to the domain is one of the most important steps in setting up your Microsoft 365 account.

Important: To perform any functions like adding, modifying, or removing domains, you must have the rights of a Domain Name Administrator or Global Administrator of a Microsoft 365 business or enterprise plan.

Let’s see how it is done.

1. Go to and click on Admins. This will take you to the Microsoft Admin Center page. (As shown in Figure. 1)

2. Once you are on the admin panel, click on the navigation menu in the top-left corner – and a drop-down will appear, as shown in Figure. 2.

3. On the Navigation Menu, Select Settings >> Domains. (You might need to click on the pull-down arrow – to see all options under Settings.)

7. Now, on the next screen, you will need to Verify your own domain name. Here, you’ll find three options. In this case, go ahead and select ‘Add a TXT record to the domain’s DNS records’ option and click on ‘Continue’.

8. Once you click on ‘Continue’ in the previous step, you will see the below screen.

You’ll need to add the TXT details – like the TXT Name, TXT Value, and TTL in your domain registrar’s or DNS hosting provider’s DNS settings.

Once done, you will have to come back to this page again to Verify the same.

Let’s see how to add a TXT record with your domain registrar. In this case, because ZNetLive is the domain registrar, we have explained the steps accordingly.

9. Go to the ZNetLive member panel to access the DNS setting for the specific domain. For that, Login to >> My Services >> List Search Services >> Select the domain>> Domain Control Center >> DNS Management

Click on the DNS settings for the domain you want to configure and click on TXT Records.

10. Click on the Edit button in front of the TXT record you want to edit.

Assign Users to the Domain

1. From the Domains list page, select the domain you want to assign users to.
